Toshiba has taken the wraps off a 55-inch, 16:9 ratio LED backlit TV with glasses free 3D capability and Quad Full HD resolution. That's a massive 3,840 x 2,160 pixels, or in other words, four times as many pixels as a 1920 x 1080p TV. We've just checked out the Toshiba 55ZL2 on the floor at IFA and the consensus is that it looks great.
